Consider a linear regression model where y represents the response variable and x and d are the explanatory variables; d is a dummy variable assuming values 0 or 1. A model with the dummy d and the interaction xd variables is estimated as y-hat = 4.5 + 0.95x + 1.5d + 0.22xd.

a.	Compute y-hat for x = 10 and d = 1. (Round intermediate calculations to 4 decimal places and final answer to 1 decimal place.)
